AC or WA

Takahashi is participating in a programming contest, AXC001. He has just submitted his code to Problem A. The problem has N test cases, all of which must be passed to get an AC verdict. Takahashi's submission has passed M cases out of the N test cases. Determine whether Takahashi's submission gets an AC.

Constraints
